轻型钢结构通常用于高层、大跨度、体型复杂、荷载或吊车起重量大、有较大振动、高温车间、密封性要求高、要求能活动或经常装拆的结构。直观的说：大厦、体育馆、歌剧院、大桥、电视塔、仓棚、工厂、住宅和临时建筑等。这是和济南轻型钢结构自身的特点相一致的。

Light steel structure is usually used in high-rise, large-span, complex shape, large load or crane lifting capacity, large vibration, high temperature workshop, high sealing requirements, movable or frequently assembled and disassembled structures. Intuitively, buildings, gymnasiums, opera houses, bridges, television towers, warehouses, factories, residential buildings and temporary buildings. This is consistent with the characteristics of Jinan light steel structure itself.

轻型钢结构通常有框架、平面(木行)架、网架（壳）、索膜、轻钢、塔桅等结构型式。其理论与技术大都成熟。亦有部分难题没有解决,或没有简单实用的设计方法，比如网壳的稳定等。

Light steel structures usually include frame, plane (wooden) frame, grid (shell), cable membrane, light steel, tower mast and other structural types. Its theory and technology are mostly mature. There are also some problems that have not been solved, or there are no simple and practical design methods, such as the stability of latticed shells.

结构选型时，应考虑它们不同的特点。在轻钢工业厂房中，当有较大悬挂荷载或移动荷载，就可考虑放弃门式刚架而采用网架。基本雪压大的地区，屋面曲线应有利于积雪滑落（切线50度内需考虑雪载）。

Their different characteristics should be considered when selecting the structure. In light steel industrial buildings, when there is a large hanging load or moving load, the portal frame can be considered to be abandoned and the grid frame can be used. In areas with large basic snow pressure, the roof curve should be conducive to snow sliding (snow load should be considered within 50 degrees of tangent).

总雪载释放近一半。降雨量大的地区相似考虑。建筑允许时，在框架中布置支撑会比简单的节点刚接的框架有更好的经济性。而屋面覆盖跨度较大的建筑中，可选择构件受拉为主的悬索或索膜结构体系。

Nearly half of the total snow load is released. Areas with large rainfall are considered similarly. When the building allows, the arrangement of supports in the frame will be more economical than the simple frame with rigid joints. For buildings with large span of roof covering, the suspension cable or cable membrane structure system can be selected.

高层轻型钢结构设计中，常采用钢混凝土组合结构，在地震烈度高或很不规则的高层中，不应单纯为了经济去选择不利抗震的核心筒加外框的形式。宜选择周边巨型src柱，核心为支撑框架的结构体系。我国半数以上的此类高层为前者。对抗震不利。

In the design of high-rise light steel structures, steel-concrete composite structures are often used. In high-rise buildings with high or irregular seismic intensity, the form of core tube plus outer frame that is unfavorable to earthquake resistance should not be selected simply for the sake of economy. The surrounding giant src columns should be selected, and the core is the structural system of supporting frame. More than half of such senior managers in China are the former. Disadvantageous to earthquake resistance.

结构的布置要根匀据体系特征,荷载分布情况及性质等综合考虑。一般的说要刚度均匀。力学模型清晰。尽可能限制大荷载或移动荷载的影响范围,使其以直接的线路传递到基础。柱间抗侧支撑的分布应均。

The layout of the structure shall be comprehensively considered according to the system characteristics, load distribution and nature. Generally speaking, the stiffness should be uniform. The mechanical model is clear. Limit the influence range of large load or moving load as much as possible, so that it can be transferred to the foundation by direct line. The distribution of lateral bracing between columns shall be uniform.

其形心要尽量靠近侧向力(风震)的作用线。否则应考虑结构的扭转。结构的抗侧应有多道防线。比如有支撑框架结构,柱子至少应能单独承受1/4的总水平力。

Its centroid should be as close as possible to the action line of lateral force (wind shock). Otherwise, the torsion of the structure should be considered. The anti-side of the structure should have multiple lines of defense. For example, if there is a supporting frame structure, the column should be able to bear at least 1/4 of the total horizontal force alone.

框架结构的楼层平面次梁的布置,有时可以调整其荷载传递方向以满足不同的要求。通常为了减小截面沿短向布置次梁，但是这会使主梁截面加大，减少了楼层净高,顶层边柱也有时会吃不消，此时把次梁支撑在较短的主梁上可以牺牲次梁保住主梁和柱子。更多相关内容就来我们网站http://www.jnghbxg.com咨询！

The layout of the secondary beam in the floor plan of the frame structure can sometimes adjust its load transfer direction to meet different requirements. Generally, secondary beams are arranged along the short direction in order to reduce the section, but this will increase the section of the main beam, reduce the floor net height, and sometimes the top side columns can not be consumed. At this time, supporting the secondary beam on the shorter main beam can sacrifice the secondary beam to keep the main beam and column.
